Hey AtakanBal 

Can you take a few screenshots to show where you are in the lab, and we can help to get some guidance to you?

Kindest regards,
Chris

      Hey AtakanBal

      If you can take screenshots of any code changes/commands you used; effectively, anything you've done so far for both Task 6 & 8, so we can see this and be in a position to provide you with the right guidance to help you complete this 😊.
